摘要(Abstract):
为研究黄土高原(Loess Plateau,LP)地区不同土质类型植被对气候因子变化的时滞响应及时变特征,选取LP地区实测气象数据(包括温度和降雨)和MOD13 A3归一化植被指数(Normalized Difference Vegetation Index,NDVI)作为实验数据,利用线性趋势分析、Mann-Kendall(MK)突变分析及皮尔逊相关性等方法对LP地区不同土质类型区域植被与气候之间的相关性进行定量分析,实验发现:由于人类活动导致LP地区的河流冲积平原土地利用情况发生变化且植被不断减少,其余区域植被均呈现显著上升趋势;由M-K趋势分析发现LP地区1981—2016年温度总体呈显著上升趋势,但2000—2016温度上升趋势不显著; 2000年LP地区实施"退耕还林"政策后,该地区温度上升速率减缓,降雨量增多(特别是在3月和5月); LP地区NDVI对气候因子存在不同时长的滞后效应,且区域性差异较大。NDVI对温度无滞后响应区域和1月滞后响应区域分别占LP区域37. 5%和62. 5%,NDVI对降雨的滞后响应时常为1~3月,分别占LP区域的62. 5%,25%和12. 5%.上述发现有助于进一步理解LP地区不同土质类型区域植被对气候响应的时间尺度,对该地区后续制定生态政策具有重要意义。
